STEAM-GEN ERATO R.

SPECIFICATION forming part of Letters Patent No. 257,236, dated May 2, 1882.

Application filed October 28, 1881.

To all whom it may concern:

Be it known that I, THOMAS G. MORSE, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsylvania, have invented new and useful Improvements in Steam and Hot-Water Generators; and I do hereby declare that the following is a full, clear, and exact description thereof, reference beinghad to theaccompanyin gdrawings and the letters or figures of reference marked thereon. Y

My invention consists in providing new and improved apparatus for the generating of steam for either heating or motor purposes, or the heating of water and the distribution of the same for heating or other purposes.

My invention relates to the construction of the boiler, the furnace, and the means for distributing hot water.

My device is shown in the accompanying drawings, as follows:

Figure l is a vertical section of all parts except the steam-dome, which is shown in elevation. Fig. 2 is a top or plan view of the boiler, the surrounding case A being in horizontal section, and the fire-grate being removed to show parts below it.

The construction and operation of my device are as follows: a

First, of the boiler. Two hollow spheres, F and G, are connected together by a tube, H. The lower end of the tube H is plugged with a bush, h, into which is screwed an internalalways opens freely into the sphere G. Horizontal tubes J radiate from the tube H at numerous points, and have within them tubes K, which radiate at correspondingpoints from the This arrangement is clearly shown in tubes J there is free access to the tubes K. Now we will suppose the device to be filled with water up to the water-lines shown in Fig. 1 in the sphere G, and that the outer surface of the spheres and the pipes H and J are exposed to heat. A movement of water will take place as follows: upward in the tubes H (No model.)

and I, outward in the tubes K, and inward in the tubes J. By adding to the device tubes M, which connect the spheres F and G, an outlet is made for the water flowing to the sphere G back into the sphere F. It will thus be seen that I have provided for a perfect circulation of water through the boiler. It will also be seen that in proportion to the capacity of the boiler a very large area of heating-surface is obtained. The caps J on the ends of the arms J may be extended laterally, as shown in Figs. 1 and 2, forming Ts, and short branch pipe j, as shown in Fig. 2, may extend from the tubes J, and in this manner considerable more heating-surface may be obtained. In the construction of this boiler the spheres should be made of castmetal and the tubes of lap-welded wrought-iron tubing of proper size. The caps J will be made of cast metal. The parts will all be connected together by screw-threads. When so constructed the boiler will be very strong and capable of resisting a very great pressure. D is the supply-pipe, and enters the boiler at the bottom. When this boiler is used for generating steam, either at high or low pressure, it will be provided with a steam-dome,

P, and safety-valve. Eis the steam-pipe leading from the steam-dome.

This boiler may be mounted in various ways. In the drawings I have shown it mounted as follows: A surrounding case of metal or brick, A, has a centrally-located pedestal, 0, within it. In the top of this pedestal is a recess containing a series of round balls, 0. The lower sphere sets upon these balls, and the supplypipe D connects with it centrally with a swivel-joint and stuffing-box c. When thus mounted the boiler can be revolved on its axis, the balls 0 acting as friction-rollers, and any one of the radial arms can be brought to the door in the case A. Such a movement will only be necessary when it is desirable to remove any of the tubes for repair. When this is donet-he fuel-magazine must be withdrawn from the case, and certain connections may have to be loosened-as for example, the steam-pipe E, if attached, as shown in Fig.1; but it is obvious that attachments may be made so as not to be disturbed.

Second, of the furnace. The case A, above referred to, constitutes the walls of the furnace. It may be made of masonry or of sheet metal. As shown it is circular. A circular grate, L, is mounted so as to surround the lower sphere, F. It rests upon rollers B, which are mounted on an annular frame, R, whichis supported by the sphere F and pipes M. The lower side of the grate is provided with coggearing L, which gears with a pinion, L",which is rotated by a detachable crank, L, on the outside of the case. By this arrangement the grate can be rotated, and the fuel put in at the 'door or other opening at one side can be caras a fuel. The magazine B isshown hinged at b,'so it can be drawn back out of the furnace when it is desired to rotate the boiler, as above described.

The plug '5 may be used when the boiler is generating steam; but it is better not to do so,

as the circulation of the water is sufficient without it, and would probably be too violent with it. The spheres F and G, assuch, are not essential elements; but by their usechamhers are obtained which are advantageous, the lower one serving as a mud-drum, and the upper one affording a steam-space. When the boiler is used for heating water only the upper sphere is wholly unnecessary; but the lower one is always desirable as a mud-drum.

To the means of circulating the water or steam in heating apparatus I make no claim in this application, but reserve my right to make a separate application therefor.

I am aware that it is not new to arrange one pipe within another, substantially as shown, for the purpose of obtaining a free circulation of steam or water.

I am aware that it is old to revolve a boiler upon a supply-pipe by means of a swivel-joint; am also aware that it is old to provide a boiler with a vertical tube having another tube contained therein, said inner tube being closed at the bottom and provided with a series of tubes radiating from near its bottom and surrounded by a similar series radiating from the outer vertical tube; also, that it is old to provide the ends of the outer radial tubes with globular projections, which furnishes a greater area for the heat to act upon; and these partsl do not claim, as they all differ from mine in that, first, the grate is not inclosed and supported by an outer series of tubes, nor are the grate and tubes revolved together; second, that the radial tubes are not arranged in series along the whole length of the vertical tubes, thus afi'ording a greater area for the heat to act upon; third, that the inner vertical tube, which is liable to clog, does not open into a mud-drum;

fourth, that the globular ends to the outer raeaaeae dial tubes are hard to remove when it is desired to clean the flues, while my T ends can be readily removed, owing to the fact that a band could easily grasp and obtain a hold upon the parts.

I claim 1.
